Title: Package leak detection
Inventor: MALLY TIMOTHY G
IPC: G01M3/36
Filed: 1993-03-19
Abstract: An apparatus and a method are provided for detecting leaks in sealed packages. The apparatus and method are particularly well-suited for an on-line system wherein each package filled and sealed on a commercial packaging line is inspected for possible leaks or seal defects. A force transducer arrangement is used, and the package is maintained at substantially constant volume while positive wall pressure over time is monitored.

IPC: C01B31/08
Filed: 1993-04-07
Abstract: An improved apparatus and method for the manufacture of activated  carbon  wherein  a  carbonaceous  raw  material impregnated with a chemical activating agent is treated by controlling the rate of heat transfer to the particles via indirect heating of the activation furnace and simultaneously introducing a flow of independently controlled sweep gas at spaced intervals along the path of travel of the particles through the furnace to more precisely control the activation reaction and the level of densification of the particles during certain stages of treatment.   In a more preferred embodiment, the particles are processed in a plurality of treatment stages related to the rate of evolution of water and/or the evolution of water and the chemical activating agent and the rates of heat transfer and the volume flow rate of sweep gas are closely controlled relative to achieving predetermined levels of densification of the particles during each  treatment  stage  and  selected  levels  of  activation properties in the end product.

Inventor: RODRIGUEZ EGA A TOMAS
IPC: B65D81/05
Filed: 1993-08-25
Abstract: A disposable packing for the transport of flat glass sheets comprising an assembly of upstanding posts made from wood and spaced from the internal walls of a container by means of a plurality of vertically spaced outwardly extending arms of which the outer ends mate with the container wall.  The inner ends of the arms are disposed on the posts at a predetermined angle relative to the outer ends so that in use the posts are inclined relative to the container walls of the container.  The posts are fixed at their base to supporting boards disposed on the floor of the container.  These supporting boards have a flexible cover where the flat glass sheet packages rest on.  The "packages" are placed one adjacent to the other and are spaced between them by means of cardboard or StyrofoamTM  spacers, there also being StyrofoamTM or plush strips disposed on the face of the upstanding posts where the lateral thrust of the glass packages is applied.  A horizontal retaining element of rectangular cross-section, having its longer sides provided with a flexible cover to rest against the inner glass packages and having a predetermined angle of inclination corresponding to the angle of the posts, forms the central horizontal fixing means for the packages.  This horizontal retaining element is located at the center of the packing and there may be one or more of such elements linked between them, these being the central fixing means for the packages.  Other longitudinal retaining elements secure the end edges of the sheet glass packages to the other walls or the floor of the container.
Patent CA-2108282-A1 (CA)
Title: Quantitative clotting assay for activated factor vii
Inventor: MORRISSEY JAMES J
IPC: C12Q1/56
Filed: 1992-04-09
Abstract: An assay for activated factor VII (factor VIIa) has been developed using truncated tissue factor (TF), a soluble mutant form of TF that retains the cofactor function of TF toward factor VIIa Unlike full-length TF, however, tTF appears not to sup-port the conversion of factor VII to VIIa. As a result, the tTF assay for factor VIIa is free from interference from factor VII in the plasma and is therefore specific for factor VIIa. The assay is much simpler than existing assays, because it is a single-stage clot. ting assay performed almost identically to a PT assay. It is also considerably more sensitive than current assays for factor VIIa in plasma. Since he tTF assay is calibrated against a factor VIIa standard, it yields an absolute concentration of factor VIIa in ng/ ml.

Title: Plate position measuring system
Inventor: ALLSHOUSE GARY W
IPC: D21D1/00
Filed: 1994-03-22
Abstract: ABSTRACT OF THE DISCLOSURE            A method and apparatus is disclosed for calibrating a gap sensing probe (12) in a refiner having first (76) and second (80) grinding plates facing each other and supported by respective first and second plate holders, each grinding plate having a face (78, 82) defining a grinding gap (86).  The gap measuring device, which is secured within one of the plates, includes a sensor probe (12) for measuring gap width data having a substantially cylindrical tip (14) with a flat frontal portion (16), an attached conical portion (18) and a longitudinal axis (20) therebetween.  A cable (22) is electrically connected to the conical portion of the probe, for transmitting the gap width data.  A protective sleeve (24) can be positioned around and contact the cylindrical tip, wherein the flat frontal portion of the tip is exposed through the sleeve.  A substantially crucible-shaped ceramic housing (28) having a closed front (30), an open back (32) is provided, wherein the flat frontal portion of the tip abuts the front of the housing and the cable protrudes from the rear of the housing.  A threaded mounting adapter (42) is situated around the housing and an adapter plug (60) is situated within the mounting adapter. The housing, the mounting adapter, and the adapter plug have flanges (38, 48, 68) and shoulders (52) which interact so as to prevent movement of the housing.  In the preferred embodiment, the probe is calibrated from the rear of the housing by turning the probe by the threaded mounting adapter.  The calibration can be completed without actually measuring the plate gap width by rotating the probe through threads which are of a known and predetermined width.

Inventor: ROGERS PHILLIP L
IPC: G01P5/26
Filed: 1992-12-04
Abstract: An optical Doppler velocimeter (10) is formed using erbium-doped fiber (82) as the lasing medium. By properly modulat-ing the lasing in the fiber, pulses of radiation are generated. Within the velocimeter, all optical signals are handled by optical fib-ers.
